* * I am not sure whether this has appeared in this newsgroup, but I am posting it anyway. There are 10 stacks of 10 dimes. You are told that one of these stacks is counterfeit(i.e all 10 coins in that stack are couterfeits). Also given that a real dime weighs 10 grams and a fake one 9. Now you are asked to find out the counterfeit stack by using a balance and and a set of weights in just ONE weighing. I may or may not post the solutions depending on the number of correct answers posted.
